The Relay16::Relay16() constructor takes no arguments, and will initialize the Relay16 object upon creation. } Relay16 Class Public Methods / Functions Relay16::Relay16() Void begin(boolean j5, boolean j6, boolean j7, char dioResetPin) It is free software, licensed under the GNU General Public License v3. The Relay16 library is copyright 2013 by Nathan Holmes and Michael Petersen. The latest source code is always available from our GitHub I2C-RELAY16 repository. At the end of the cycle, it'll turn on all the relays, then turn them off, and start over. It will cause the relays to turn on, in order, for a quarter of a second. Once the library's in place, you should be able to open up the relay16_example.ino sketch and build/upload it. You still need to install the library itself, as described in Setup. Real developers don't read the documentation first, just shut up and show me some code, sparky!)Ī sample Arduino sketch that demonstrates some simple uses of the library is available as part of the source package - it's in the 'relay16_example' directory. You'll also likely need to import the stock 'Wire' library to get I2C functionality. Once the files are there, start your Arduino IDE and you should be able to pick 'Relay16' from 'Sketch->Import Library.' to add it to your sketch.

More details can be found in the Arduino - Libraries documentation. This is known as 'Manual Installation' of an Arduino library.

You'll need to copy the Relay16 directory (with the Relay16.cpp and Relay16.h files) into your arduino/libraries directory. The 6P6C connectors on the board implement the standard Iowa Scaled Engineering 6P6C I2C connector pinout, making it directly compatible with a wide variety of shields we offer with an I2C port. If the /IORST is left floating, the board will hold itself in a permanent reset state and do nothing. Optionally, the /IORST (inverted IO reset) line can be connected to a digital I/O pin or just connected to +3.3V or +5V. The board itself needs to be connected to the SCL and SDA lines coming out of the Arduino, as well as ground.

The Relay16 library was designed to make the Iowa Scaled Engineering I2C-RELAY16 control board easy to use with the Arduino TM environment. I2C-RELAY16 Library Reference Introduction
